* include/lpc24xx.h: Added AHB and EMC defines. Fixed Ethernet status
sizes.
* include/system-clocks.h, misc/system-clocks.c: Added micro seconds
delay function that uses Timer 1. Changed PLL setup.
* network/network.c, startup/bspreset.c, startup/linkcmds.lpc2478,
startup/linkcmds.lpc2478_ncs, startup/linkcmds.lpc2478_ncs_ram: New
